Description

Technical Field

[0001] This invention relates to the field of glass pressing technology, specifically to a linear combined glass pressing machine. Background Technology

[0002] The pressing and molding of glass products (such as vessels, bottles, optical components, etc.) is usually carried out using mechanical or hydraulic presses. Molten glass is dripped into a mold, pressure is applied to fill the cavity, and then it cools and solidifies. Traditional glass pressing and molding equipment is mainly divided into single-station presses and multi-station rotary presses.

[0003] Existing rotary presses use a rotary indexing mechanism to sequentially complete different processes at various stations, achieving continuous operation to some extent. However, rotary presses have the following drawbacks:

[0004] First, the existing rotary drive mechanism and mold opening and closing arrangement are difficult to arrange, which limits the rigidity and stability of the whole machine;

[0005] Secondly, since the upper and lower molds are installed on different parts of the turntable, misalignment is likely to occur, resulting in defects such as uneven wall thickness and flash in the products; especially at high cycle times, the inertial load is large, and the positioning accuracy decreases.

[0006] Finally, the heating and cooling systems of rotary presses are difficult to arrange, they occupy a large area, and it is difficult to achieve an integrated setup from preheating and pressing to cooling.

[0007] Therefore, a glass pressing machine capable of continuous, efficient, and linear combination is provided. Summary of the Invention

The various embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0045] Example 1

[0046] Please see Figures 1 to 14The present invention preferably provides the following technical solution: a linear combined glass pressing machine, comprising: a base plate 111, two sets of end beams, the two sets of end beams being disposed on both sides of the base plate 111 and supporting an interlocking rigid chain module between them; the interlocking rigid chain module includes an upper mold carrier chain 213 and a lower mold carrier chain 212, wherein the upper mold carrier chain 213 has a plurality of upper molds 720 linearly arranged on it, and the lower mold carrier chain 212 has a plurality of lower molds 611 corresponding one-to-one with the upper molds 720 linearly arranged on it; and a first dual-drive linkage servo system and a second dual-drive linkage servo system disposed on the two sets of end beams, and a crossbeam 112 is also horizontally assembled between the two sets of end beams, and a transmission mechanism is mounted on the crossbeam 112. The wedge block assembly; the first dual-drive linkage servo system and the second dual-drive linkage servo system drive the upper mold carrier chain 213 and the lower mold carrier chain 212 in the storage state to mesh and unfold, interlock and move forward to the other end of the end beam frame, open and retract, thereby synchronously driving several upper molds 720 and lower molds 611 to pre-close and demold in sequence along the forward direction, and under the action of the transmission wedge block assembly, the upper molds 720 and lower molds 611 in the pre-closed state are finally closed and pressed; the crossbeam 112 is equipped with heating components and cooling components in sequence along the running direction of the interlocking rigid chain module, which can provide auxiliary preheating and cooling for the upper molds 720 and lower molds 611 in the moving state.

[0047] In this application, such as Figure 1 , 2 As shown in Figure 3, through the cyclic meshing and unfolding action of the upper mold carrier chain 213 and the lower mold carrier chain 212 of the interlocking rigid chain module, in conjunction with the dual-drive linkage servo system, multiple sets of upper molds 720 and lower molds 611 can correspond one by one along the forward direction and complete the entire process of pre-molding, final mold closing, demolding and re-folding in sequence. This structure realizes continuous step-by-step assembly line operation, which greatly improves the pressing output per unit time and is suitable for large-scale mass production.

[0048] Secondly, a first dual-drive linkage servo system and a second dual-drive linkage servo system are used to drive the upper mold carrier chain 213 and the lower mold carrier chain 212 from both ends. This dual-drive synchronous control can ensure that the upper and lower chains maintain a precise alignment relationship during engagement, unfolding, and travel, avoiding uneven load or crawling caused by unilateral drive. At the same time, the final mold closing and pressing is completed in conjunction with the transmission wedge block assembly. The wedge block action can provide a stable and uniform mold clamping force, ensuring that the closed positions of the upper mold 720 and the lower mold 611 at each station are consistent, thereby obtaining highly consistent glass product dimensions.

[0049] Furthermore, heating and cooling components are sequentially arranged along the running direction of the interlocking rigid chain module. These components represent existing mature technologies and will not be elaborated upon here. Figure 1 , 2The heating plate 811 and cooling plate 911 in the middle can heat or cool the mold in different positions in sections. They can provide auxiliary preheating and controllable cooling for the moving upper mold 720 and lower mold 611. This layout allows the mold to reach a suitable temperature before reaching the mold closing area, which is conducive to the flow and filling of glass droplets. After pressure molding, it immediately enters the cooling zone to achieve rapid cooling and shorten the molding cycle of a single product.

[0050] It adopts a working mode of storage, engagement and unfolding, continuous pressing, opening and storage. While ensuring pressing accuracy and quality, this glass pressing machine significantly improves production efficiency, while reducing operating costs and maintenance difficulty, and has high industrial practical value.

[0051] Furthermore, each set of end beam frames includes two upright plates 211 arranged in an inverted U-shape and a top plate 415. Each upright plate 211 has a second loop groove 2112 and a first loop groove 2111 in its upper and lower parts, respectively. The second loop groove 2112 and the first loop groove 2111 converge in the middle of the upright plate 211 to form a straight groove 2113. The second loop groove 2112 and the first loop groove 2111 can respectively accommodate the upper mold carrier chain 213 and the lower mold carrier chain 212 and guide them to mesh and move forward in the straight groove 2113. The upright plate 211 is also equipped with two sprockets 2114. The two sprockets 2114 are respectively located at the corner positions of the second loop groove 2112 and the straight groove 2113, and the first loop groove 2111 and the straight groove 2113 and respectively mesh with the upper mold carrier chain 213 and the lower mold carrier chain 212.

[0052] Through further provided end beam frames, such as Figure 3 , 6 As shown in Figures 7, 8, and 12, each set of end beam frames adopts an inverted U-shaped structure (consisting of two upright plates 211 and a top plate 415). Guide channels, a second loop groove 2112 and a first loop groove 2111, are respectively set in the upper and lower parts of each upright plate 211. The two channels converge in the middle to form a straight groove 2113 in the interlocking area. This design allows the upper mold carrier chain 213 and the lower mold carrier chain 212 to travel along independent tracks before entering the interlocking area, avoiding mutual interference. They naturally close at the convergence point, ensuring the alignment accuracy of the upper and lower molds 611 during the pre-molding stage. Simultaneously, the two sprockets 2114 at the corners mesh with the upper and lower carrier chains respectively, guiding the chains to turn smoothly, preventing jamming or tooth stripping, and ensuring the smoothness and repeatability of chain operation.

[0053] Furthermore, the first dual-drive linkage servo system and the second dual-drive linkage servo system have the same structure. The first dual-drive linkage servo system includes a dual-axis motor 411 mounted on the top of the top plate 415, two bearing seats 412, wherein the two bearing seats 412 are located on both sides of the dual-axis motor 411 and are respectively rotatably mounted with a first transmission wheel 413, and connecting horizontal shafts 414 are mounted on the shaft ends on both sides of the dual-axis motor 411. The two connecting horizontal shafts 414 extend to both sides and are respectively connected to the first transmission wheel 413. A gearbox 418 is also mounted in the middle of the vertical plate 211. Two meshing gear bodies are installed inside the gearbox 418. One end of the two gear bodies extends to the inner side of the vertical plate 211 and is respectively connected to two sprockets 2114. The other end of one of the gear bodies extends to the outer wall of the gearbox 418 and is connected to a second transmission wheel 417. A transmission belt 416 is connected between the second transmission wheel 417 and the first transmission wheel 413.

[0054] Through further configuration of the first dual-drive linkage servo system and the second dual-drive linkage servo system, such as Figure 1 , 6 As shown, the two shaft ends are driven by a dual-axis motor 411, and the horizontal shaft 414 extends to the left and right to connect the first transmission wheel 413 located on both sides. The second transmission wheel 417 is driven by a transmission belt 416, which in turn drives the two meshing gear bodies inside the gearbox 418. This avoids the problem of asynchronous speed that may occur when using two independent motors, and fundamentally ensures the consistency of driving on the left and right sides.

[0055] Secondly, the two meshing gear bodies inside the gearbox 418 are connected to the left and right sprockets 2114 respectively. The gear meshing forces the rotation speed to be equal and the direction to be opposite, thereby ensuring that the linear speed of the upper mold carrier chain 213 and the lower mold carrier chain 212 is completely consistent on the left and right sides, preventing mold misalignment or chain crawling caused by speed difference.

[0056] Preferably, either the first dual-drive linkage servo system or the second dual-drive linkage servo system can be selectively driven to operate, such as... Figure 1 As shown, in the forward pressing process of the upper mold 720 and the lower mold 611 from left to right, the first dual-drive linkage servo system can be driven to push the molds on it to close in sequence. When the upper mold 720 and the lower mold 611 are close to the right side for demolding, the second dual-drive linkage servo system works to pull the molds on it to demold in sequence.

[0057] Example 2

[0058] In another embodiment of the present invention, each upper mold 720 includes a second rectangular frame 7206 and first lugs 7207 connected to both ends of the second rectangular frame 7206 for fixed assembly with individual links on the upper mold transport chain 213 on both sides. Each of the four corners of the second rectangular frame 7206 is provided with a first elastic telescopic post, and a second movable plate 7205 is provided at the outer end of the first elastic telescopic post. A mold head 7212 penetrating the second rectangular frame 7206 is mounted on the second movable plate 7205. Furthermore, the second movable plate 7205 is provided with upper wedges 7201 at both ends that are adapted to the transmission wedge assembly; the first elastic telescopic column includes a second movable column 7208 fixed on the second movable plate 7205, the second movable column 7208 passes through the through hole on the second rectangular frame 7206 and is connected to a second limiting ring 7209, a third spring 7211 is sleeved on the outer wall of the second movable column 7208 between the second limiting ring 7209 and the second rectangular frame 7206, and a positioning shaft 7210 is connected to the bottom of the second limiting ring 7209.

[0059] Furthermore, each lower mold 611 includes a first rectangular frame 6113, with second lugs 6112 at both ends of the first rectangular frame 6113. The second lugs 6112 extend to the adjacent position of a single link of the upper mold carrier chain 213 and are fixedly assembled with the single link of the lower mold carrier chain 212. Second elastic telescopic pillars are provided at each of the four corners of the first rectangular frame 6113, and a first movable plate 6118 is provided at the bottom of the second elastic telescopic pillars. A mold base 6111 penetrating the first rectangular frame 6113 is mounted on the first movable plate 6118. The mold base 6111 and the mold head... 7212 is adapted, and the first movable plate 6118 is provided with lower wedges 6119 adapted to the transmission wedge assembly at both ends; the second elastic telescopic column includes a first movable column 6114 fixed on the first movable plate 6118, the first movable column 6114 passes through the through hole on the first rectangular frame 6113 and is connected to a first limiting ring 6116, a second spring 6115 is sleeved on the outer wall of the first movable column 6114 between the first limiting ring 6116 and the first rectangular frame 6113, and a positioning sleeve 6117 adapted to the positioning shaft 7210 is connected to the top of the first limiting ring 6116.

[0060] Furthermore, the transmission wedge assembly includes two sets of transmission wedges 113, which are respectively placed in the opposite parts of the upper mold 720 and the lower mold 611, and each transmission wedge 113 has a transmission wedge surface 1131 at both ends. The transmission wedge surface 1131 can be adapted to the upper wedge 7201 of the upper mold 720 and the positioning sleeve 6117 of the lower mold 611.

[0061] In this embodiment, an upper mold 720, a lower mold 611, and a transmission wedge assembly are further provided, such as Figure 5 , 6As shown in Figures 10 and 11, the upper mold 720 is provided with a first elastic telescopic column (a second movable column 7208, a second limiting ring 7209, a third spring 7211, and a positioning shaft 7210), and the lower mold 611 is provided with a second elastic telescopic column (a first movable column 6114, a first limiting ring 6116, a second spring 6115, and a positioning sleeve 6117). When the interlocking rigid chain module drives the upper mold 720 and the lower mold 611 in the pre-closed state to move forward, the transmission wedge surface 1131 at the end of the transmission wedge block assembly can interact with the upper wedge block 7201 and the first movable plate 6118 and produce inclined transmission. At the same time, the first elastic telescopic column and the second elastic telescopic column are compressed, and the upper and lower mold heads 7212 and mold base 6111 are close to each other and complete the pressing and closing of the mold.

[0062] And such as Figure 10 As shown, the positioning shaft 7210 at the bottom of the elastic column of the upper mold 720 and the positioning sleeve 6117 at the top of the elastic column of the lower mold 611 are mutually adapted to form a guide positioning. During the mold closing process, the positioning shaft 7210 and the positioning sleeve 6117 are first roughly aligned, and then the mold head 7212 and the mold base 6111 are finely guided. The double guidance ensures the concentricity of the cavity of the upper and lower molds 611 and the plane fitting accuracy.

[0063] like Figure 1 As shown, the transmission wedge assembly includes two sets of transmission wedges 113, which interact with the upper wedge 7201 of the upper mold 720 and the lower wedge 6119 of the lower mold 611, respectively. Each transmission wedge 113 has a transmission wedge surface 1131 inclined surface at both ends. As the interlocking rigid chain module moves forward, the mold closing process is realized.

[0064] like Figure 7 , 11 As shown, the upper mold 720 is fixed to a single link of the upper mold carrier chain 213 via a first lug 7207; the lower mold 611 is fixed to a single link of the lower mold carrier chain 212 via a second lug 6112, and the second lug 6112 extends to the position of the adjacent link, achieving a compact and staggered arrangement. The mold and the chain are connected by detachable lugs, allowing for quick mold replacement without disassembling the chain, significantly reducing downtime during production transitions; at the same time, the lug positioning surface ensures the consistency of the relative position of the mold after each installation.

[0065] Furthermore, the thickness of the two transmission wedges 113 increases gradually along the forward direction while maintaining a certain distance;

[0066] like Figure 5As shown, the two transmission wedges 113 are respectively placed on the opposite side of the upper mold 720 and the lower mold 611, and their thickness increases gradually along the forward direction of the chain. As the interlocking rigid chain module moves forward, the gap between the transmission wedges 113 and the matching parts (upper wedge 7201 and lower wedge 6119) on the mold gradually decreases, thereby continuously and gently increasing the squeezing force on the upper and lower molds 611.

[0067] This design effectively reduces the impact load caused by the instantaneous application of high pressure by traditional cylinders or hydraulic cylinders, effectively protects the mold cavity edges and elastic telescopic pillars, and prevents the glass droplets from generating flash or internal stress concentration due to instantaneous pressure. At the same time, the gradual pressurization is conducive to the full flow and filling of the glass melt in the cavity.

[0068] Secondly, after reaching the maximum thickness, the two drive wedges 113 maintain a certain distance (i.e., an equal thickness section). Within this range, the extrusion pressure of the drive wedges 113 on the mold remains at a constant maximum value, providing a stable pressure-holding stage for glass pressing.

[0069] Example 3

[0070] In another embodiment of the present invention, a long groove 1132 is provided on a group of transmission wedges 113 near the upper mold 720, and several auxiliary tube assemblies are provided on the long groove 1132. The several auxiliary tube assemblies can slide horizontally in the long groove 1132 and are connected by a long spring 1134. The auxiliary tube assembly at the end is fixedly connected to the inner end of the long groove 1132 through a connecting block 1133 and is connected to an air pump. The remaining several auxiliary tube assemblies are connected to a vacuum pump. Each auxiliary tube assembly includes a connector tube 512 and a U-shaped tube 511 connected to the connector tube 512. Both ends of the U-shaped tube 511 are respectively connected to connecting pipes 513. The outer wall of each connecting pipe 513 is connected to There is a long slider 515 that slides within the long groove 1132. The long slider 515 passes through the long slider 515 and is connected to a limit block 514 at the top. A transmission wedge 517 is connected to its bottom. A first spring 516 is connected to the outer wall of the connecting pipe 513 between the transmission wedge 517 and the long slider 515. A central cavity 7214 is provided in the middle of the mold head 7212. Air extraction holes 7213 communicating with the central cavity 7214 are opened on both sides of the central cavity 7214. The two ends of the central cavity 7214 extend to the position of the upper wedge 7201 and are connected to the through slot hole 7204. A groove 7202 is opened on the upper wedge 7201. A wedge groove 7203 adapted to the transmission wedge 517 is provided on the groove 7202.

[0071] Furthermore, it also includes electromagnets 5151 disposed on both sides of the long slider 515, and a long magnetic strip 1135 disposed on the inner wall of the long groove 1132 and adapted to the electromagnets 5151, for controlling the magnetic attraction limit of each auxiliary tube assembly.

[0072] In this embodiment, through further configured auxiliary tube components, such as Figure 3 , 4 As shown, the auxiliary tube assembly at the end is connected to the air pump, and the remaining components are connected to the vacuum pump. Figure 8 , Figure 9 As shown, when the upper mold 720 moves to the corresponding station and docks with the auxiliary tube assembly, the vacuum pump actively evacuates the cavity after mold closing by passing through the auxiliary tube assembly, the docking tube 513, the through slot 7204, the central cavity 7214 and the air extraction hole 7213. This design can effectively remove residual air between the glass melt and the mold cavity, eliminate air bubbles inside the product and surface pores. At the same time, vacuum assistance can promote the rapid flow and filling of the glass melt in the complex cavity, and improve the molding integrity of thin-walled or deep-cavity products.

[0073] At the very end, the air pump is under positive pressure. Before pre-demolding, it can be switched to blowing air. Compressed air is blown into the mold cavity or the surface of the product through the same air path. For glass products that are prone to sticking to the mold, short-term positive pressure blowing can help the product separate from the mold. At the same time, blowing air can remove the debris that has seeped into the pipeline and the air extraction hole 7213, reducing the risk of blockage of the air extraction hole 7213.

[0074] Secondly, such as Figure 3 , 4 Several auxiliary tube assemblies can slide horizontally within the long groove 1132 and are connected in a string by long springs 1134. The end auxiliary tube assembly is fixed by a connecting block 1133, while the others can move relative to each other. This allows the auxiliary tube assemblies to follow each closed upper mold 720 and lower mold 611, ensuring reliable docking of the wedge groove 7203 of each upper mold 720 with its corresponding transmission wedge block 517 interface, as shown in the figure. Figure 5 As shown, when the transmission wedge 113 applies a continuous and gentle extrusion force, the end auxiliary tube can move together with the mold to achieve continuous and synchronous vacuuming operation.

[0075] Furthermore, each auxiliary tube assembly is equipped with an electromagnet 5151 on both sides, which, together with the long magnetic strip 1135 on the inner wall of the transmission wedge 113, form a magnetic attraction limiting pair, such as... Figure 8 and 9 As shown, when docking or disengaging is required, the magnetic attraction can keep the corresponding auxiliary tubing assembly stationary, such as... Figure 7 , 9As shown, when the mold reaches the corresponding station, if the auxiliary tube assembly remains magnetically attracted and stationary, under the action of the first spring 516, the transmission wedge 517 is inserted downward into the wedge groove 7203 position, and the connecting tube 513 and the through slot hole 7204 are connected. After the auxiliary tube assembly is released from magnetic attraction, the auxiliary tube assembly can run with the mold. When it is necessary to release the vacuum, the auxiliary tube assembly is made stationary again. Under the transmission action of the wedge groove 7203 and the inclined surfaces on both sides of the transmission wedge 517, the connecting tube 513 is lifted and the first spring 516 is compressed, so that the upper wedge 7201 where the upper mold 720 is located passes over the auxiliary tube assembly to separate the two.

[0076] Example 4

[0077] In another embodiment of the present invention, the two sets of end beams are respectively provided with a first pipe and a second pipe at opposite ends, and the first pipe and the second pipe have the same structure and extend to the starting end and the ending end of the upper mold 720 and the lower mold 611 respectively. The first pipe can be connected to the glass raw material solution tank for feeding the glass before pressing, and the second pipe can be connected to the water spray device for cleaning the upper mold 720 and the lower mold 611 after demolding. The first pipe includes two mounting strips 312, which are respectively vertically fixed on the other two crossbeams 112, and a horizontal pipe 311 is arranged horizontally between the two mounting strips 312. The middle part of the horizontal pipe 311 is connected to a vertical pipe 313, and its bottom is connected to several material distribution pipes 314.

[0078] In this embodiment, it is cleverly combined with an interlocking rigid chain module, such as Figure 3 , 12 As shown, the discharge ports of the first and second pipe structures are located precisely in the middle of the initial position of the upper mold 720 and lower mold 611 in the pre-closed state. This does not affect the operation of the upper mold carrier chain 213 and lower mold carrier chain 212, nor does it affect the forward movement or retraction of the upper mold 720 and lower mold 611. The first pipe is connected to the glass raw material solution tank. Its structure includes two mounting strips 312 vertically fixed on two crossbeams 112, a horizontal pipe 311 horizontally connecting the two mounting strips 312, a vertical pipe 313 connected in the middle, and several distribution pipes 314 connected at the bottom. Molten glass enters the horizontal pipe 311 through the vertical pipe 313, and then is evenly distributed at the starting end through multiple vertically downward distribution pipes 314.

[0079] Furthermore, the second pipe is connected to the water spraying device, which has the same structure as the first pipe and is located at the other end of the end beam frame. When the upper mold 720 and lower mold 611, which have completed demolding, pass through this area, the water spraying device cleans the molds through several material distribution pipes 314.

[0080] Specifically, two products under this design are provided, such as Figure 1 , 14The spacing between the interlocking rigid chain modules is relatively long. At this time, the shape of the mold base 6111 and the mold head 7212 is preferably a long disc structure. Under the action of the interlocking rigid chain modules, when the mold head 7212 closes in the direction of the mold base 6111, a long glass object can be formed.

[0081] When the spacing between the interlocking rigid chain modules decreases, the short mold base 6111 and the mold head 7212 can be assembled. For example, when the mold head 7212 and the mold base 6111 change from an elongated shape to an approximately circular shape, a shape like... Figure 15 Another type of glassware product.
